The performance of most of the fiber-reinforced concrete pavement projects in the United States (34 projects built since 1971) are reported. These include experimental street and highway projects as well as more recently constructed fullscale airport pavements. While a few have performed well, many have developed defects early in their service lives. The lessons learned should help engineers to design future projects that will provide better service. Careful consideration, and perhaps additional research, is needed in the areas of joint design and spacing, load transfer at joints, fiber content, and thickness design.
